Abstract
A kind of wide special-shaped fire cover of burning area, including fire cover body are the utility model is related to, fire cover body is equipped with the interior pyrosphere more than a circle being made of some interior fire holes and the outer burning ring more than a circle being made of some outer fire holes；Fire cover body is equipped with above oblique cut at one, and at least partly outer fire hole is located on oblique cut.The beneficial effects of the utility model are as follows：By setting oblique cut, and the outer fire hole in part is arranged on the oblique cut, the flame mouth-shaped of the outer fire hole produces deformation, outer burning ring is set to obtain the effect of inner outside burning, so as to effectively expand the burning area of outer burning ring, so that the integral combustion area of fire cover also increases therewith, the efficiency of combustion of this fire cover is effectively increased, and reaches the requirement of level-one efficiency.
Description
Technical field
A kind of fire cover is the utility model is related to, is specifically a kind of wide special-shaped fire cover of burning area.
Background technology
The shape of existing fire cover is typically all the annular element for possessing standard shape, and outer burning ring and/or interior pyrosphere are all arranged at
On ring surface, cause burning position single, and burning area is small, can be to reach level-one efficiency, therefore, it is necessary to existing
Fire cover is further improved.
The content of the invention
The purpose of the utility model is to overcome above-mentioned the shortcomings of the prior art, and provide a kind of design simple conjunction
Reason, and by setting oblique cut, effective expansion outer burning ring prolongs burning area, makes the increase of integral combustion area coverage, and energy
Reach the wide special-shaped fire cover of the burning area of level-one efficiency.
What the purpose of this utility model was realized in：
A kind of wide special-shaped fire cover of burning area, including fire cover body, fire cover body are equipped with more than a circle by some interior
The outer burning ring more than interior pyrosphere of fire hole composition and a circle being made of some outer fire holes；It is characterized in that：On the fire cover body
Equipped with above oblique cut at one, at least partly outer fire hole is located on oblique cut.By setting oblique cut, make on outer burning ring
Burning area increase, combustion efficiency is more preferable, and can reach level-one efficiency.
The oblique cut is set to fire cover body central inclined upward, and is set more than at two, and annular is distributed in fire
On lid body.Oblique cut can effectively expand the combustion range of outer fire hole, and by uniformly distributed arrangement, the bottom of a pan is heated
It is even.
According to the actual requirements, the oblique cut is inclined arcwall face or inclined plane.
The fire cover body is equipped with planar annular, and a circle above outer burning ring is arranged on planar annular, and oblique cut is set
It is placed in the edge of planar annular.The outer fire hole in part is arranged on planar annular, reaches the effect burnt in the inner part；The outer fire in part
Hole is arranged on oblique cut, reaches the effect burnt in the outer part, and the combination in interior outside increases the combustion range of outer burning ring.
The fire cover body is equipped with circular cone, which is set to fire cover body central inclined downward, a circle
Pyrosphere is arranged on the circular cone in above, and interior pyrosphere is arranged on circular cone, effective concentrate firepower, it is ensured that centre bit
The combustion efficiency put.
To reach optimal combustion efficiency, the outer fire hole is radially outwardly sloping setting, and gradient a is 50 ° -70 °, excellent
Select 60 °；The endogenous fire aperture is set to sloping inwardly, and gradient b is 20 ° -40 °, preferably 30 °.
The beneficial effects of the utility model are as follows：
By setting oblique cut, and the outer fire hole in part is arranged on the oblique cut, the flame mouth-shaped of the outer fire hole
Deformation is produced, outer burning ring is obtained the effect of inner outside burning, so as to effectively expand the burning area of outer burning ring, so that fiery
The integral combustion area of lid also increases therewith, effectively increases the efficiency of combustion of this fire cover, and reaches level-one efficiency
It is required that；In addition, oblique cut and circular cone are obliquely installed, make that there is many places gap between fire cover and the bottom of a pan, carried for burning
For enough oxygen, make full combustion of fuel, avoid producing pernicious gas, improve safety in utilization.
Brief description of the drawings

Embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
Referring to Fig. 1-Fig. 4, the wide special-shaped fire cover of this burning area includes the fire cover body 1 of annular, fire cover body 1 it is inside and outside
Side is respectively equipped with the interior pyrosphere and one that a circle is made of some interior fire holes 3 and encloses the outer burning ring being made of some outer fire holes 4；Fire cover sheet
1 top edge of body is equipped with oblique cut 2 everywhere, and the outer fire hole 4 in part is located on oblique cut 2, the outer fire hole 4 on oblique cut 2
Burn in the outer part, with reference to the outer fire hole 4 that other burn in the inner part relatively, can effectively increase the burning area of outer burning ring entirety,
So as to increase the burning area of this abnormity fire cover entirety, efficiency of combustion is improved, reaches the requirement of level-one efficiency.
Further, oblique cut 2 is obliquely installed to 1 overcentre of fire cover body, and annular is distributed in fire cover body 1
On, it is ensured that the bottom of a pan is heated evenly；Oblique cut 2 is inclined arcwall face.
Further, the top of fire cover body 1 is equipped with planar annular 5, and outer burning ring is arranged on the planar annular 5, and inclination is cut
Face 2 is arranged at the edge of planar annular 5, and the outer fire hole 4 on planar annular 5 burns in the inner part, the outer fire hole on oblique cut 2
4 burn in the outer part, so as to increase burning area.
Further, the inner side of fire cover body 1 is equipped with circular cone 6, which inclines to 1 central lower of fire cover body
